How Polarographic DO Technology Works:
Polarographic dissolved oxygen sensors are based on the Ross and Clark polarographic measurement method. The sensor consists of a platinum cathode and silver anode electrodes. The HI7041S electrolyte solution (concentrated potassium chloride) is held in place over the electrodes by a PTFE (polytetrafluoroethylene) membrane.
When an external voltage is applied to the platinum cathode, silver anode, electrolyte solution, and gas-permeable membrane, a current is established that is directly proportional to the concentration of dissolved oxygen in the sample. The electrolyte solution acts as the conductive medium, making its quality and proper maintenance critical for accurate measurements.
Why Proper Electrolyte Matters:
The electrolyte solution is crucial to polarographic DO probe performance. Depleted, contaminated, or incorrect electrolyte leads to slow response times, drift, and inaccurate readings. Regular replacement with HI7041S ensures optimal sensor function, fast response, and reliable dissolved oxygen measurements.
Professional Applications:
Essential for aquaculture operations, wastewater treatment facilities, environmental monitoring, laboratory research, hydroponics systems, and any application requiring accurate dissolved oxygen measurement. Keep spare bottles on hand to maintain uninterrupted testing capability.
